AC/DC guitarist Angus Young was asked in an interview with a Swiss radio station asked which AC/DC album he'd “put on to impress someone who has never heard the group” and he chose their album, Let There Be Rock, from 1977.
Angus explained that his older brother George, who was producing the album, asked him and his other brother in the band, Malcolm, what they wanted it to sound like. “And Malcolm just looked at [him], and he said, ‘We just want an album that’s just gonna be pure hard rock guitar.’”
Angus "thought that was great, because everyone else in the world was into whole other genres – there was punk music, there was new wave -- all this other stuff was coming out." He just thought, "This is pure magic," and "that album defined AC/DC in his eyes. He says that was when he went, ‘This is a great band.'”
